Unfortunately, I can not find a hacker Outpost.
Have the systems Quirin and Atorat in galaxy 2 follow.
Can someone help me please
Do I need more besides the anarchy OXP?
I often met a Renegade Viper. Is that hacker Viper leading you to the hacker Outpost? Unfortunately always fired on me. No matter if my status was clean or offender. What I fired back until she begged me to stop shooting. What I followed her. Without success. Even further shooting on them brought no result. Except that it was destroyed sometime.

One way to at least determine if there is indeed a Hacker Outpost spawned would be to check the active entities in the system. You will need the Test Release version of the game and the Debug Console for this (check the downloads page at oolite.org for more on that). Launch the console, then launch the game, then go into the system where the Hacker Outpost is expected. Then pause the game and press '0' (zero). The list of entities in the system will be written in Latest.log, complete with their coordinates in the system. You can inspect that Latest.log and see where exactly the Outpost is.

Thanks for the tip.
I have followed your description and searched in the Latest.log for "hacker" and "outpost". Both terms were not found. Which means that there is no hacker Outpost.
In my view, there are two possible causes for this:
1. There is no HAcker Outpost in the system.
2. It lacks an OXP that creates the hacker Outpost or something prevents it.

I would be in several anarchies now. Every time I checked the Latest.log, in none of the systems was a hacker outpost.
That would mean that something about my Oolite and OXp is wrong. But I do not know what. Am grateful for every tip where I can look for the mistake
